When I uplink items from my Iphone, I usually leave them there since I want to show them to friends.
In Lightroom, I work on them, modify them, delete the ones I don't like, but these changes (or those I make on the IPhone) do not sync with each other.
The next time I sync, all images I have deleted get re-instated.
Let me know if I'm wrong, or how I could get around it. Perhaps sync should exist between iPhone and Lightroom to prevent this.
